Abstract
A terrain modeling method that fuses geometric characteristics and mechanical characteristics, and a terrain modeling system are provided in the present invention. The method includes steps of: obtaining color images and depth images of the detected region, performing a terrain semantic segmentation on the color images, and fusing ground semantic information obtained by the semantic segmentation and depth information contained in the depth images at the same time to generate the point clouds; mapping the point clouds to a raster map in a map coordinate system to generate corresponding rasters, and updating the elevation values to the corresponding rasters; and calculating the input images in terms of terra-mechanical characteristics, and updating calculation results to the corresponding rasters to generate a terrain model. A mechanical characteristic parameter is added to a terrain factor, and terrain characteristics are innovatively performed from two dimensions of geometric characteristic and mechanical characteristics.
